as for the nuke Vs rock's
as space is a vacume IE no (or very minisquele amounts of particules) in this vacume then its my GESS that a nuke would have to be inbedded in to the taget rock or lomp of STUFF, to have any effect at all. this will NOT need a bunch of nuti-go-lucky oil riggers
but a ICBM(s) or simmeler type of missle(s) with a penetrater type noses to be used to bast the think offcorse.
